llVlPROVElVIENTlN WICKS FOR LAMPS.

Specification forming part of Letters Patent No. 36,277, dated August 26, 1F56?.

To @ZZ whom, z'ft may concern:

Be it known that we, JosEPH'H. CoNNELLY and .JOHN COOK, of Vheeling, in the county of Ohio and State of Virginia, have invented a new and Improved Lanip-/Vick; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in Which- Figure l is a longitudinal outside View of a piece of wick. Fig. 2 is a longitudinal view of one hal f of the wiclgshowing the in ner side. Fig. 3 is a transverse section of the same.

Similar letters of lreference indicate Corresponding parts in the several figures.

This invention consists of a tubular lamp- Wick having a nap on the inner side, by which the capillary attraction is more perfectly developed, and it is made to constitute a better conductor and to facilitate the ascension of the heavier kinds of oil and to serve equally well for the lighter oils and illuminatingfluids, forming a perfect feeder for all kinds of illuminating oils and lluidsin the market, and Y preventing explosions by providing for the free escape of any superabundant generation of gases or vapors in the lamp.

This internally-mapped Wick may be manufactured in various ways. That which is represented in the drawings' is composed of two strips, (t ci, of canton-flannel, each of double the intended width of the wick. The two ledges of each are folded over on the napped side to meet in the center of the strip, as shown at b in Fig. 2, and pressed flat, as shown in Fig. and the two strips are laid one on the other with the edges of the two together, as shown in Fig. 3, and stitched together by a Sewingmarhine or by hand close t0 the folds, as shown at c c in Figs. l and 3, thus forming a double tube with the nap on the inside of each tube. rlhe canton-flan nel may be cut into strips and folded by suitable machinery.

Another mode of manufacturing the wick is to weave it in tubular forni, and either to produife a nap on the inner side by suitable apparatus or to raisevthe nap on the outside and afterward turn it inside out and press it fiat. A third mode of manufacturing it is to weave a web of double the intended width of the wick with a selvage on each side, and then to fold it either in the center or in such manner as to bring the selvages together in the middle ofthe web, and then-press it flat and stitch along both edges or folds, as shown in Fig. 1..

The capillarity of the wick made by either of theabove modes may be increased by interlaying it with a thin layer` of rawcotton next the napped surface. y

Vhat we claim as our invention, and desire to secure by Letters Patent, is-

A tubular wick having a nap on its inner surface, substantially as herein described.
